Muaj peb lub ntsiab smelting txoj kev rauxim av aluminium oxidesmelting: tsau rauv smelting txoj kev, dumping rauv smelting txoj kev thiab exile smelting txoj kev. Vim qhov loj peev txheej ntawm exile smelting, txoj kev ruaj khov rauv smelting thiab dumping furnace smelting txoj kev yog siv tam sim no.
Kev sib piv ntawm cov khoom corundum smelted los ntawm ntau txoj kev:
1. Lub corundum uas tsim los ntawm lub qhov cub tawg (txoj kev) muaj ntau cov siv lead ua aggregates, cov siv lead ua me me, qib iav siab thiab muab faib rau ntawm cov ciam teb, yog li qhov toughness tsis zoo, lub brittleness yog loj, cov nplej abrasive yooj yim poob. tawm, tus kheej-sharpening yog zoo, thiab lub compactness yog zoo. Ntau haum rau consolidated abrasives thiab cov ntaub ntawv refractory.
2. Lub corundum tsim los ntawm frit furnace (txoj kev) muaj ob peb siv lead ua aggregates, loj siv lead ua loj, thiab me me iav zoo, yog li nws muaj tsis zoo brittleness, siab toughness, thiab zoo hnav tsis kam. Vim lub loj crystals, zoo toughness thiab brittleness, lubxim av fused aluminatsim los ntawm txoj kev smelting no yog tsim nyog rau kev tsim cov coated abrasives. Yog li ntawd, nws tseem yog feem ntau siv abrasive nyob rau hauv zus tau tej cov abrasive siv.
3. Cov tshuaj muaj pes tsawg leeg, theem muaj pes tsawg leeg thiab lub ntiajteb txawj nqus ntawm corundum uas tsim los ntawm cov kwj smelting txoj kev yog sib npaug rau cov uas tsim los ntawm txoj kev frit. Crystal loj, microhardness, siv lead ua qauv, thiab compressive zog tau qis me ntsis rau txoj kev exile dua rau txoj kev frit. Qhov no yog vim hais tias cov xim av corundum tsim los ntawm txoj kev raug tshem tawm muaj cov yam ntxwv ntawm microcrystalline corundum hauv cov yam ntxwv no. Txawm hais tias nws yog me ntsis qis dua li txoj kev frit, nws pom tau tias zoo dua hauv kev siv.
Kev tsim khoom thiab kev sib piv ntawm corundum smelted los ntawm ntau txoj kev:
1. Exile plaub hau: nruam ntau lawm, high degree ntawm automation, tab sis loj peev, complex qauv, haum rau high-power smelting.
2. Txoj kev pov tseg: kev tsim khoom tas mus li, qib siab ntawm kev siv tshuab, kev nqis peev me me, kev tsim khoom zoo, ib txoj kev uas tau siv dav tam sim no.
3. Txhim kho txoj kev (frit method): tsis tu ncua ntau lawm, qib qis ntawm kev siv tshuab, tab sis kev nqis peev me me, cov khoom siv yooj yim thiab cov txheej txheem yooj yim. Nws yog txoj hauv kev tseem ceeb rau corundum smelting hauv me me abrasive factories tam sim no.
